Just got a new pistol, new on the market. Don't want to name the gun because I will assume for now it could be my reloads. Anyway, I had about 6 rounds out of 100 that misfired. Firing pin hit but no bang. After cleaning the gun thoroughly 3 of the 4 I tried went bang. Brass was new Starline, powder was TiteGroup, WLP primers, all loaded on a Dillon press. I never had a misfire with these same loads in my 1911's. This is a striker fired pistol with a rectangular firing pin. Cases seem OK in the case gauge. Ideas?? Where to start?? I would try them in another pistol but I'm currently waiting on my Baer to come in and I'm 1911 naked at the moment.
